Application 'filed March T 0 all whom t may concern.'

Be it known that l, Trroinis Coon, subject of the King,` of Great Britain and lreland, and resident of Stalybridge, in the county of Chester, England, have invented certain improvements in Baling- Presses, of which the following` is a specification.

rlhis invention relates to improvements in baling presses for use in the balingv of all kinds of materials which require to be compressed into a small compass and it consists in the novel construction and combination of the parts hereinafter 'lully described and claimed.

l have found that in compressing material in balingpresses that where considerable density is attained it is difficult to remove the compressed bale even when the movablepressed platen is moved away from the bale owing to the ends of the latter or the sides exerting outward pressure against the rigid press box sides or ends and so setting` up considerable friction which act-s to prevent the easy removal of the bale.

ln order to avoid the defect referred to my invention consists essentially in the eniployment of a pivoted and movable side or end of the press box chamber which during compression can be moved and held by a system of levers and links in a position parallel to the opposite end or side and after compression can be allowed to fall away from the bale so as to allow of the latter to be taken out of the press box vquite easily.

lily invention will be fully described with reference to the accompanying;` drawing in which- Fig. 'l is an end elevation of a. baling press of the vertical type showing the application of my invention thereto and Fig. Q, partial front elevation of saine.

ln carrying out my invention ll use a sheet metal or other suitable plate o usually, though not necessarily, extending` from the base of the press to the head o, suoli plate also extendingV between the ordinary side doors c of the press. fitting freely against the parts named. l/Vhere a sheet metal plate is employed it is usually strengthened at its outer side by being secured to plates Z of angle or l section so as to resist the internal pressure set up during compressing` the bale. At the lower end the plate is provided with pivot pins e or a shaft suitipecincation of Letters Patent.

ably secured to it and mounted in bearings formed in brackets j attached to the frame of the press. On the other hand the brack- .ets may be provided with pivot pins passing into bearing brackets fixed to the plate. rlhe latter can move freely about the pivotal points so that the plate can be brought into the vertical position as shown by dotted lines in Fig. 2 which corresponds with its position during the compressing of the bale but allows it to be inclined outwardly when it is desired to take the bale out of the press box. in order to move the plate and hold it in the vertical position whilst compressing is taking` place l employ one or more arms g fixed upon a shaft 7L mounted in brackets 7l secured to the compressed frame the free ends of said arms carrying bowls or rollers j for bearing against the plate. The shaft has also fixed upon it an outwardly extending` arm k to the free end of which is coupled the upper end of a link ym the lower end of which is coupled at n to a handy. lever 0 pivoted at j; to the machine frame. rlhe arm or operating,- lever 7c is arranged at an angle to the arms g, and it projects upwardly when the arms g are horizontal. l/Vhen the levers and links are in the position indicated in the drawings, the arms g are at right angles to the plate a so holding` the latter in the vertical position and resisting the expansive stresses of the bale material. By moving` the hand lever 0 downwardly the arms g can be raised so as to allow the plate a to assume an inclined position about its pivotal points and so release the bale and allow it to be removedfrom the press readily.

The arrangement described may be applied to one side of the press when end doors in place of side doors are employed. The arrangement may also be used in conjunction with other types of vertical presses and also to horizontal presses with slight modifications depending; upon the character of the press and without departing from the essential feature of my invention.

What l claim as my invention and desire to secure by Letters Patent is rl`he combination, with a press box provided with av side which is pivoted to it at one end, of a rock-shaft journaled in bearings secured to the press box and arranged parallel to its pivoted side, arms secured on the rock-shaft and provided with rollers for bearing against the pvotecl side and In testimony whereof I have hereunto holding it in place, an operating lever seset my hand in the presence of two Wtlo Cured to the rook-Shaft and Iarranged at an Ilesses. angle to vthe salcl arms,` a lhmclV lever pv-` otecl to the press box and arranged substantally parallell to the operating' level, lltnesses: and a connecting-rod pvotelly connecting TWILLIAM H A'TAYLOR, the two said levers. .v L.
